On difference equations of Kravchuk-Sobolev type polynomials of higher order
Roberto S. Costas-Santos, Anier Soria-Lorente
In this contribution we consider sequences of monic polynomials orthogonal with respect to Sobolev-type inner product \[ \left\langle f,g\right\rangle _{λ,μ}\!=\!\sum_{x=0}^Nf(x)g(…
On second order q-difference equations satisfied by Al-Salam-Carlitz I-Sobolev type polynomials of higher order
Carlos Hermoso, Edmundo J. Huertas, Alberto Lastra +1
This contribution deals with the sequence of monic polynomials, orthogonal with respect to a Sobolev-type inner product related to the A…
Hiding data inside images using orthogonal moments
Anier Soria-Lorente, Stefan Berres, Ernesto Avila-Domenech
In this contribution we propose a novel steganographic method based on several orthogonal polynomials and their combinations. The steganographic algorithm embeds a secrete message…
A steganographic approach based on the chaotic fractional map and in the DCT domain
A. Soria-Lorente, E. Pérez-Michel, E. Avila-Domenech
A steganographic method based on the chaotic fractional map and in the DCT domain is proposed. This method embeds a secret message in some high frequency coefficients of the image…
Analytic properties of some basic hypergeometric-Sobolev-type orthogonal polynomials
Roberto S. Costas-Santos, A. Soria-Lorente
In this contribution we consider sequences of monic polynomials orthogonal with respect to a Sobolev-type inner product \[ \langle f,g \rangle _{S}:= \langle {\bf u}, f g\rangle +N…
A single parameter Hermite-Padé series representations for Apéry's constant
Anier Soria-Lorente, Stefan Berres
Inspired by the results of Rhin and Viola (2001), the purpose of this work is to elaborate on a series representation for which only depends on one single intege…
